They both have the same software. The 16IZ adds integration for the CGY760 heli gyro.

The IZ has a lipo battery and USB charging
The SZ has a NiMH pack and wall wart charger

The IZ has a new case, new gimbals and a better screen.

Over all for me it is a no brainer to get the 16IZ. It is a newer radio, lots of improvements and costs less.
